GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 242,116, dated May 31, 1881.

Application filed May 7, 1880.

To all whom it may concern:

Be it known that LDAVID D. DEVOL, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Binding Attach ments for Harvesters, of which the following is a specification.

Myinvention relates to improvements in devices-for aiding in separating the gavels from the inflowing grain, as delivered from the elevator upon the binding-table or receiver of a harvester having an automatic binder, and in a device for retaining the bundle upon the verge of the binding-table, away from the unbound grain; and the objects of the improvements are to makeacomplete separation of the gavel and move it away from the rest of the grain toward the verge of the table during the binding, and to retain the bundle on the verge of the table, and move back therefrom toward the unbound grain all the straggling grain which may have been drawn away by the removal of the gavel, and even and straighten up the unbound pileof inflowing grain preparatory to separating another gavel. l attain these objects by means of the mechanism hereinafter described and claimed,and as illustrated in the accompanying drawings, in which- Figure 1 is an end elevation showing the devices in position and ready to separate a gavel. Fig. 2 is a side elevation showing the devices in position to return forasecond gavel. Fig. 3 is a detail showing a side view of the gear-wheel and crank-arm detached. Fig. 4 is an end view of a harvester with the binding attachment mounted thereon; and Fig. 5 is a plan view of the binding attachment, illustratin g the relative arrangement and operation of its parts.

Similar letters of reference indicate similar parts throughout the several views. 0 t

A is a binding or gaveling arm. B is a dividing-needle. This arm and dividing-needle make a simultaneous oscillating movement upon the binding-table 0 from the point where the grain is delivered upon the table by the elevator to the verge of the table, the arm being depressed just previous to its movement toward the verge of the table and elevated previous to its backward movement, and the (No model.)

needle being rapidly elevated and projected up through the binding-table (which is. rovided with a segmental slot for the needle to trawl in) during the first one-third, or less. of its movement toward the verge of the table, and suddenly depressed during the last third, or less, of its backward movement, so thatits point shall descend to thelevel of or below the surface of the binding-table, to allow the grain to fall back of theneedle as soon as the pileisstraightened. The gavel is separated by the bindingarms movement down and the dividing-needles movement up, and is carried or slid toward the verge of the table by their simultaneous movement in that direction. All of the straggling grain which may have followed the gavel is swept back toward and to the pile of inflowingunbound grain on the table, and the pile is straightened and squared up by the backward movement of the dividing-needle before it is depressed.

A is a post, so pivoted as to be rotated back and forth. The binding-arm is pivoted to this post, so that its free end having the divider may rise and fall,but its connection to the post laterally is rigid, so that a rotary movement of the post back and forth will give a corresponding oscillating movement to the arm. A crank-arm is formed of two pieces, a a, united at one end and connected by a socket-joint to the flanged wheel 0 at a point some distance from its center. The other ends of the pieces a a are spread apart, and are pivotallysecured to post A ,upon its opposite sides. This crank is connected with the binding arm by a rod, D. The rotation of the wheel 0 gives a crank movement to that end of the crank-arm connected to said wheel, so that said crank-arm, by itsrod-connection with the bindin g-arm, and by its vertically-pivoted and rigid lateral connections with the post, giving the post a rotany motion back and forth, imparts to the binding-arm both its vertical or risin g-and-fallin g, and its horizontal or swinging movements. The post A also carries a rigid arm, B, which travels under the receiver or binding-table and carries the dividing needle B in its forwardand-backward movement. This rigid arm carries a slide, 1), which hangs below the outer end of the arm and supports the lower end of the dividing-needle, to which is secured afriction-roller, b. This roller runs in an inclined slide or stationary cam-track, E, which is so curved as to produce the desired up-and-down movement of the dividing-needle by means of the roller following the track.

F is a vertical retaining-needle, located at the verge of the binding-table and supported on a hinged bar, F, which is connected to a supplemental forked bar, (i, whose prongs embrace and fit into the groove of a grooved pulley, H, secured to its shaft eccentrically. This shaft and eccentric-pulley II are given an intermittent motion by means of a cog-gear, II, and square head h upon said shaft, which engage with the flanged wheel 0. This latter wheel has portions 0 of its periphery, on opposite sides of the wheel, provided with cogs, and portions 0 of its flange, alongside of the cogged portions, cut away, so that the head It slides along on the flanged parts and prevents the shaft from revolving, while the shaft is permitted to revolve when the head It is passing the unflanged parts 0, and whilethe gear-wheel H, engaging with the cogged portions, causes the shaft to revolve, thus producing the intermittent motion. 3y means of the intermittent rotation of the eccentric-pulley within the forked lever connected to the needle-bar the retaining-needle F is projected up through a hole in the verge of the binding-table at the proper time to pierce the bundle as soon as its outward motion ceases, and retain it at the verge of the table during the backward movement of the dividing-needle l3, and is drawn down to relieve the bundle just previous to the arrival of the next bundle, so that the lirst will be discharged by the second, and so on.

When the binding attachment is mounted on the machine it may be supported on the frame G of the machine, as shown in Fig. 4.

The machinery which operates the bindingarm and two needles should be located beneath the binding-table and operated by any suitable belt or gear connecting with the moving maehinery of the harvesteras usuallyconstructed, so as to cause the arm and needles to work with the required speed to bind the grain into bundles as fast as cut and delivered upon the table.

I do not wish to be limited to the precise machinerydescribed for operating the arm and needles, as it maybe varied to produce the like result by any reciprocating device.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. In a grain-binder, a dividiugaleedle, B, vibrating arm B, slide I). and track E, combined and operatin substantially as and for the purpose specified.

2. In a grain-binder, a vibrating dividingueedle, 1;, operating to sweep back the straggling grain, in combination with a retainingneedle, F, located at the verge of the table and operated by a vibrating lever, which causes said retai ning-needleto be projected up through a hole in the binding-table, and pierce and retain the bundle while the straggling grain is swept back, substantially as specified.
